To all whom 'it may concern:

Be it known that L'THOMAs W. MORRELL, a citizen of the United States,and a resident of the'town of Bloomfield, county of Essex, and State ofNew, Jersey, have invented certain new and useful Improvements in Games,

- of which the following is a full, clear, and exact description. 0

My invention relates to improvements in metal joints for window glass,particularly to the small panes of irregular outline employed in stainedglass Windows to make a composite pane. Y

Heretofore metal strips of ductile, flexible metal in I form have beenused to constitute the uniting joint between panes. For this purposelead cames were commonly used, but the difficulty was encountered thatthe joint between the metal and glass could not be satisfactorilysealed; there being no close union of parts the panes so fastened werenot water proof. To. overcome this a plastic binder was used, but it wasfound that, when dried these binders failed to adhere to the cames andglass, due to the hard smooth sur- I faces of the metal and glass. Acame was next devised having its heart, or that part forming the webuniting the doubly flanged top and bottom, milled, affording increasedfrictional area for the binder of cement employed; this provedinadequate, due to the limited anchorage afforded the cement and to itseffective cohesion being solely directed to the edge of the pane.Thereafter cames were devised having the flanges so formed by thelead-press that their inner faces were grooved with a series oflongitudinally extending parallel recesses for the reception of thecement, the heart being similarly grooved with a series of dovetailcorrugations. These grooves were formed by the die forming the came andwere continuous. Such grooves or recesses have proved to be a source ofWeakness, in that as compared with cames of equal weight, the flangesand heart are found to lose the slight stiffness which the non-elasticmetal possessed,. and the cames so constructed are readily bent and losetheir cement or other binding material, the lead not being inherentlystrong enough to bear the strain incidental to their purpose. Toovercome this objectioncames have been devised with hearts of tinnedsheet-iron and others of all hard metal. These forms are expensive anddo not readily adapt themselves to art glass work.

The object of my invention is to provide a came of lead having, forgiven equal weight, first: the strength of a solid came; and second: theincreased contact area for cement or other binder of the grooved came. Iaccomplish these objects by the construction hereinafter described andillustrated in the accompanying drawings in which like referencenumerals indicatesimilar parts in the several views.

' Figure 1 is a perspective view of a came embodying my improvedfeatures of advantage.-, Fig. 2'is a view in cross-section of same,while Fig. 3 illustrates the inner faces of one pair of flanges, a camebeing shown in horizontal section. Fig. 4 is a view similar to Fig. 3,but shows the application of the came, fragments of two pane or piecesof glass being shown. Fig. 5 is a view similar to Fig. 2, but also showsthe application of the came, two adjoining panes or pieces of glassbeing shown as jointed by the came.

1 is the heart, core or web which is shown as preferably milled.

2 is the upper double flange and 3 the lower double flange.

4 are cusps or pockets formed in the inner faces of the flanges, bothupper and lower. 5, 5 are panes of glass. These cups 4, 4:, are formedafter the came is drawn from the die of the lead-press, by indentation,no metal being removed, as in the 'case of the grooved or recessedcames; As this series of indentations does not constitute a continuousabsence of metal, the weakness due to such a construction is obviated.

My improved came has all the stiffness of solid metal, while affordingrepositories for the cement or binding material, and may be formed inthe process of manufacture as at present practiced by means similar tothat employed in milling the heart, without increasing their cost.

Having thus described my improvement, I claim as my invention:
